Subject: [Boost-users] Simple example program builds but hangs when I run it. (Ubuntu).
From: vincegata (vincegata_at_[hidden])

I run Ubuntu 11.04. I downloaded Boost 1.48.0, then I followed the
instructions from Getting Started on Unix variants to build the libraries
into /usr/local/include and /usr/local/lib. Now, I build the Simple example
program without any errors, however
when I run the program it just hangs indefinitely on std::for_each() line.

Could someone help me with this please?

$: g++ -g -lboost_filesystem main.cpp

#include <boost/lambda/lambda.hpp>
#include <iostream>
#include <iterator>
#include <algorithm>

int main()
    using namespace boost::lambda;
    typedef std::istream_iterator<int> in;

    std::for_each(in(std::cin), in(), std::cout << (_1 * 3) << " " );
    int stop = 1;
